If I understand you correctly, you have a mesh that you act upon 
(rotate/translate/whatever) and then want to go back to the original mesh 
and act again with a different set of rotations/translations.

If so, then the easiest way is to store the mesh on hard disk during the 
first frame and at every following frame load it from disk and apply 
whatever you want to apply. That way you don't have to undo anything but 
start fresh with every frame.
